I've been carrying my Shield 9mm with Federal HST. Any suggestion for what to carry for my Benelli M4 for home defense?

I have a Shield 9mm with Shield RMS carried in AIWB with a Atlas G-Hook Belt and Federal HST. I decided that to get a Benelli m4 for home defense for a two story house. Longest hallway is about 60 feet which leads to the front door. Looking for the best home defense shotgun ammo. via /r/CCW http://ift.tt/2hh6gW5
